reverse engineering unity games?

[suletta]

i saw what mattkc did with sonic runners, and it inspired me to try it with the game djmax technika q. unfortunately, the newest version of that game uses il2cpp. i mostly want to reverse engineer it for the sake of porting to 64-bit android and pcs. i'm mostly confident that trying to use an old game client would break private server functionality, which is vital for the game's operation. any help? thanks in advance.
